sPEcIFIoA'rIoN forming par'of. Letter; Patent No. 423,504, dated Maren is, 1890. 1 Application sied November 1`2, 188e. serial No. 3so,os4. (No modem' T all whom t may concern.-

Be it'known that I, MILO BROWN WIBLE, a citizen of the'United States, residing at Arcata, in the county of Humboldt and State of California, have invented certain new and useful Improvements in Swinging Gates; and I do declare the following' to be a fullgclear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,`reference being had to the acconipany,

ing drawings, and to the letters of `reference marked thereon, which form-a part of this specification.

My'invention relates to gates, and especially to swinging gates, which' arevadapted to be opened from either sidei by a person approaching them in a vehicle or on horseback.

The invention resides' in certain improvements in the automatic latches andihe'mechanism for operating the gate, ashereinafter described, and particularly pointed out in the claims. 'if' In the drawings, Figure ljis a perspective View of my gate represented in ac losed position. Fig. 2-is a modified form of yoke.

The gate A is preferably composed of metal v tubes a, united by suitable couplings a', which form a light but strong and durable structure. It is hinged to the gate-post B by means of a pintle at its lower corner and a pintle a2 at its upper corner, the former entering a socket t and the latter projecting up through a hole c in the yoke C, which is suitably pivoted on a stud b', so as to be rotatable Yin a horizontal plane. The yoke is preferably diamond-shaped, as shown, with itslonger axis transverse to the plane of the gate when closed. The pivot-hole for the stud 'b' is substantially at the center of the diamond, the hole c being at one side of the pivot and in the line of the minor axis. At each end of the yoke is an upright pin c', and at the corner opposite the hole c is another upright pin Cords or chains D are attached to the C2: pins c and then led behind the pin c2, and thence to latch-posts E, set in the ground at a distance from the fence equal to the length of the gate. An arm near the top of each post supports a pulley E', over which the cordDpreferablypasses. On the'end of each cord is a handle D', which may be weighted.

The cord may run to a separate post or to .a tree conveniently situated. i "The gate is provided with a pivoted latch F, adapted to play vertically in a guide as.

The gate-post Gis provided with an improved catch to engage with said latch when the gate is shut. A plate His secured to the post, and,

ifdesired, additional posts G. may be erected on each sideof the gate-post to afford a firmer The inner them. lPivoted to the plate under each flange is a dog h', whose outer end or tail is heavier than the nose, which is thereby held normally in contact with or near to the under side of the iange adjacent to its inner end. The upper edge of each dog slants upwardlytoward the nose, so that the space between the ange and the dog is V-shaped. The plate is arranged at such a height from the ground that when the gate is in a closed position the end of the latch F will lie between the ends of Athe two dogs and their overhanging flanges, as shown.

On each latch-post E is fastened a plate I, having a single overhanging flanget' and dog t', similar to those on the plate H, and adapted to be engaged by the latch F when the gate is opened. A stop-flange i2, against which the latch strikes, prevents the gate from swinging too far open. NVhen closed, one of the dogs h serves as a stop to prevent the gate from swinging past the post G.

The operation is as follows: The gatek being shut, as shown, a pull on the cord D turns the yoke C on its pivot, thereby conveying the pintle o? vtoward that side of the gate away from the operator and back toward the line of the posts E E. This tilts the gate over slightly and lifts the free end of it far enough to raise the latch F up through the space between the ends of the iianges. The tilting tends to swing the gate open, since its tendency is always to assume a position in the plane passing through the three pivots a2 b b. As soon as the latch F is lifted above the flange h it no longer opposes the inclination of the gate to swing open, and as the gate passesiiby the plate H the latch yrides up over the inclined iiange h, dropping to its normal position when the platey has been cleared. The inertia of the gate carries it into line-with the post E, upon reaching which the latch F strikes the dog and rides up its back until it strikes the under 'side of the flange i, when the nose of the dog has passed through and Wishes to shut the gate, he gives a pull upon the cord at the post to which the gate is locked open, turning the yoke back to the position shown in the drawings and causing the latch to be lifted frombetween the dog z" and the stopiiange 712 and the gate to be swung into a closed position, where it automatically latches itself, as before.

It will thus be seen thatl my gate can be automatically unlatchedo from the gate-post G and swung open or released from the posts E and closed by simply pulling on the cord D, and .that in either case the automatic catches will hold it in the position to which it is swung.

. The pivoted latch F permits the gate to .be

opened by hand without lifting it or tilting it, and the overhangin g iian ges partially protect the dogs from the weather. `The upright pins c c2 allow the cords D to have considerable range of movement vertically, so that the gate can be operated perfectly well on a hill, where one post E must be set higher than the fence and the other post lower.

' v In some cases, as with a light gate, the yoke maybe provided with downwardly-projectinglugs or fingers C', which will engage with the top rail of the gate when the yoke has made about a quarter of a revolution and positively throw the gate in the direction in which the yoke is turned.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, isY

1. COIllbinaitiOD 3f (rate haivg @Il ing at the rear of the pin c2, substantially asV described.

2. The combination, with a gate having the upper pintle 0,2, of a yoke C,pivotally mounted on the gate-post, having a hole to receive said pintle, and vprovided with two downwardly-projecting fingers C', adapted to engage with the top rail of the gate, substantially as described. V

3. The combination, with the plate H, provided'with the two inclined flanges h, having an open space between their inner ends, of the dogs h', pivoted to the plate below the flanges and having their noses adjacent to the inner ends of said flanges, substantially as described.

4t. The combination, with a gate having a pivoted latch, of means for tilting the upper pintle of the gate to one side and tothe rear and thereby raising the front end of the gate, a catch provided with a dog and a stop, between which the latch normally rests, and an inclinedfflange overhanging the dog and .up which the latch will ride when the gate is tilted and lifted, substantially as described.

5. The combination, with a gate having a pivoted latch kF,"ofa catch consisting of a downwardly-inclined Lfiange and a dog pivoted y MIL() BROWN WIBLE. Witnesses:
